CHIMNEY.

Application filed January 7, 1924. Serial No. 684,783.

To all ywhom. z' may concern:

Be it known that I, THRODORE G, JOHN- soN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri,` have invented certain new and useful Improvements in Chimneys, of which the following is a specification.

My invention relates to improvements in chimneys and one object is to utilize a large percentage of heat which has heretofore gone to waste by radiation from the sides of and by escape from the top of the chimney, for the purpose'of heating the rooms in the building equipped with said chimney.

A further object is to provide controlling means whereby the heat from the chimney may be distributed in. substantially a uniform manner to the rooms adjoining the chimneyV on' different oors, or concentrated to a large extent in any one of said rooms.

Another object is to utilize the chimney as a ventilator in the summer season, to the end that warm air may be drawn from the adjoining rooms and a good circulation of air created to reduce the temperature.

Other objects will hereinafter appear, and in order that the invention may be fully understood reference will now be had to the accompanying drawings, in which:

Fig. l is a broken vertical sectional view of the chimney and a portion of the basement and iirst floor of the building.

Fig. 2 is a vertical sectional view of a continuation of the chimney and a portion of the irst and second floors of the building.

Fig. 3 is an enlarged fragmentary perspective view of a portion of the chimney.

Fig'fl is an enlarged broken horizontal section on line IV-IV of Fig. 1. Y

Fig. 5 is an enlarged broken horizontal section on line V-V of Fig. l.

Fig. 6 is a detail of the topmost valves and mechanism for actuating the same.

Referring now to the different parts, A designates a portion of the basement, B a portion of the first floor, and C a portion of the second floor of a building equipped with the chimney l, which is preferably located between two adjoining rooms as shown by Figs. 1 and 2, so that the heat radiated from the four walls of the chimney may be utilized for heating said rooms instead of a portion going to waste as would be the case if the chimney were located outside of the building.

D designates a furnace or other heater having a pipe E connected thereto for carrying off the smoke and other products of comJ bastion of the chimney l.

2 designates a jacket ofsuitable material surrounding all but the doors of the furnace I) and also a large portion of the pipe E to form a warm air chamber 3 in which the heat radiated from the furnace E and the pipe F is collected and delivered to the first floor B through a suitable register G, provided with the usual adjustable louvers g for controlling the passage of air through said register G.

fl designates the brick or other masonry walls of the chimneyl. Said walls l are preferably lined with tile 6 and have lateral openings 8 leading to the floors B and C, and a lateral fresh air opening l0 communieating with the basement A. The openings S and l0 are provided with registers 12 and I4; having the usual adjustable louvers 16 and 18, respectively, for controlling the passage Of air through said registers, which may beef any well-known form.

19 designates a smoke stack arranged centrally within the chimney l and communieating with the upturned end of an elbow f connected to the pipe E. Said smoke stack 19 is of less diameter than the interior of the chimney l in order to leave an intervening air shaft 2O which extends preferably throughout the length of said chimney.

The greater portion of the smoke stack 19 consists, preferably, of sheet metal or other heat radiating sections having slip joint con- -nectionsg the uppermost sect-ions being surmounted by nonrusting tubular tiles 22, the topmost one of which has a marginal flange 24, projecting over the upper end of the air shaft 20.

The air shaft 20 is divided into a plurality of chambers by horizontal division plates 25 and QG, the margins of which are embedded in the chimney walls 4. Said division plates 25 and 26 reinforce the chimney walls l and have collars 28 into which the smoke stack i9 snugly lits and whereby it is held centrally within the chimney l. rShe division plates 9,5 and 26 have ports 29 and 30, respectively through which latter the passage of air is controlled by valves 32 preferably arranged in pairs as shown by Figs. 3 and 4. Each pair of valves 32 is iixedly mounted upon a. shaft 34 journaled in bearings 36, embedded in the chimney walls 4. All but the topmost shafts Sli are provided with cranks 4G whereby they may be rocked to open or close the respective valve 82. rlhc shafts of the topmostvalves 32 are provided Tith levers 42 having depending chains la connected to levers 48 mounted on shafts loperable from the upper floor C by cranks 45.

46 designates upwardly extending conical baffles for concentrating the air in the shaft 2O around the smoke stach 19, which extends centrally through said baffles, and 48 designates downwardly extending conical baffles for directing a portion of the heated air towards the registers 12.

50 designates a gas or other suitable burner arranged in the lower portion of the chimney 1 for accelerating the draft therein when desired.

52 designates a clean-out door in the lower portion of the chimney 1, and 5d a large door also at the lower portion of said chimney through which access may be had thereto when installing the slnolre stack 19.

In practice it is apparent that when a fire is built in the furnace D the sinolre and other products of combustion in ascendin through the pipe E and smoke stack 19, will through radiation, heat the warm air chamber i?) and the air shaft 20, which latter supplied with fresh air from the l ement A through the register 14. As the warm air ascends in the shaft 2O it is heated by being directed against the smoke stack 19 by the baflles 4.6 and portion of the heated air is directed towards the regist 12 by the baffles 4S. By proper manipulation of the registers 12 ,ose

and thevalves 32, the heated air within the air shaft 2O may be either concentrated in anyY one room adjoining the chimney 1 or discharged in substantially a uniform inanner throughout all of sa'id rooms as preferred. as the warm air escapes from the top of the air shaft 2O it is deflected by the flange 2l away froin the vent at the upper end of the smoke stack 19, and hence will not interfere with the draft thereof by causing conflicting air currents.

From the foregoing description it is apparent that have produced a chimney einbodying the advantages above pointed out, and while have shown and described the preferred construction, combination and arrangement of parts, l reserve the right to inalie such changes as properly fall within the spirit and scope of the invention as claimed.

Having thus described my invention, what .l claim and desire to secure by Letters Patent, is:

ln combination a chimney having openings in its side for the passage of air, a smoke stack arranged within said chimney and spaced from the inner surface thereof to leave an intervening air shaft which coininunicates with said openings in the sides of the chimney and reversely disposed conical baffles extending around the smoke stack in the air shaft for directing the air therein toward and away from the smoke stack.

In testimony whereof I a'lv'nx my signature.

THEODGRE G. JOHNSON.
